While displaying the slide, ask the class the following questions:

• Is the height of a chair correct?
• Are there any pressure points?
• Is the worker's posture ok?
• Is the worker keeping her hands in proper position?

Suggested Responses:

• Chair height is good because the workers feet are flat on the ground and their thighs are horizontal.
• There don't appear to be any pressure points between the worker's body and the chair.
• Worker's back is straight, and there is a gap between the workers' legs and the seat of the chair.
• Worker's posture is good.
• Backrest appears to be adjusted to the right height.
• The worker's hands are hanging - an elbow rest should be used.
